Under section 269P of the Customs Act 1901 this Order declares that specific imported goods — plate-mill parts described as "couplings and coupling halves" (tariff classification 8483.60.90) — are goods to which item 50 in Part III of Schedule 4 to the Customs Tariff Act 1995 applies, effective 8 October 2007. It affects importers, customs brokers and manufacturers because it sets which Schedule 4 tariff treatment applies; the Order stays in force until revoked under sections 269SC or 269SD (signed by a CEO delegate).
